Start with their own heartbeat
Why human physiology should be taught from the student's body outward — and the two-finger pulse lab that opens my year.
Read entry →13 years teaching Biology to Grades 8–12. My students culture their own bacteria, key out campus trees, and can explain their own heartbeat from ion channel to emotion. Biology done with wet hands and open windows.
I spent my Ph.D. years counting phytoplankton and my weekends teaching my niece to key out garden weeds — and eventually admitted the weekends were the real work. Thirteen years later I run biology like a naturalist's apprenticeship: microscopes always out, windows always open, and a campus biodiversity register that students guard like a family ledger.
My lab cultures its own yogurt bacteria, raises moths through full metamorphosis every monsoon, and keeps a 63-species campus register that has twice caught the groundskeeper felling the wrong tree. Along the way: 241 NEET qualifiers, a 96% board average at peak, and a steady stream of alumni who send me photographs of lichen from their honeymoons.
If your school wants biology taught as an encounter with the living world — dissection-tray rigour plus open-window wonder — transplant me. I establish quickly in most habitats.
Thirteen years from cell membrane to biosphere — everything labelled.
Biology is the only subject the student carries inside their own body — and we somehow teach it from diagrams of someone else's. My classes start with the nearest living thing: your pulse, the moss on the water tank, the curd setting in the canteen. Name it, watch it, culture it — and the textbook becomes a field guide to a world they've already touched.
Lead a four-teacher department. Moved to weekly wet labs, built the campus biodiversity register (63 species and counting), and run the NEET biology stream — 241 qualifiers with a 96% board average alongside.
Grades 9–12 biology; started the monsoon moth-rearing tradition and the pond-water Fridays that made microscope time the most requested period in school.
Phytoplankton ecology research; discovered that explaining mitochondria beat isolating them. Left with a Ph.D. and a permanent microscope habit.

Read entry →My son made the family do a 'transect walk' on holiday and identified fourteen plants. Fourteen. We used to just call it 'the garden'.
Ishaan's motherPARENT · GR 11The biodiversity register her students keep stopped us felling a nesting tree. It's now school policy to check with Grade 10 first.
PrincipalVIDYA NIKETAN SCHOOLI survived NEET biology because she made us draw everything. In my anatomy vivas now, I can still see her margin notes.
